To all whom 'it mayvooacem:

Be itknown that we2 CHARLES II. JACOB- sEN and CARL BREER, citizens of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Power-Transmitting Joints, of which the following is a specification.

The device forming the subject matter of this invention is designed to transmit motion from a motor to a device such as a gas pump through a joint that is perfectly sealed and which will remain perfectly sealed for an indefinite period. It is particularly useful with relation to gas pumps or compressors used in domestic ice machines although we do not wish to be limited to this particular application of the joint in its broader aspects. l

The invention is illustrated in the accompanying drawings as follows Figure 1 shows a side elevation, partly in section, of the invention applied to a reci rocating pump.

ig. 2 a similar view of the invention as applied to a rotary pump.

In the construction shown in Fig. 2, 1 marks the compression chamber, 2 a rotary pump, 3 the drive shaft for the the drive shaft, 5 a motor, 6 the shaft of the motor, and 7 a crank mounted on the motor shaft. The crank 7 has a ball S formed thereon andV a wabbling bar 9 forms a ball joint with the ball 8 and a similar ball joint 4. A wabbling joint fulcrum 11 has a spherical surface 12 which' operates in the Spherical bearings 13 in a wall or partition 14. It will readily be seen that as the motor rotates an orbital movement is given to the motor end of the bar 9 and asimilar orbital movement given to the opposite end, thus rotating lthe crank 4 vand operating the pump 2. The bar operates on 4the wabbling fulcrum 11 in transmitting this movement. v

The pump as lshown is designed for a domestic ice machine and it is essential to the success of these machines that the leakage of gases from them -be prevented. On the other v hand such machines run for long periods with little or no attention and consequently the joint through which the power of the pump is transmitted is one of vital importance. In the present structure to obviate the leakage from the intake chamber 18 of the pump lthrough the joint through which pump, 4 a crankon` 'veying the movement of vthe motor and pump;

power is delivered we utilize a bellows diaphrag is mounted on the fulcrum 11 and the opposite end is secured to the wall 14, as shown the wall having a lip- 17 and the diaphragm a flange 16 which extends over the lip. Bellows diaphragms of this type have been used for'various purposes and will last for long periods even though subjected to action such as is indicated in this structure.

' 15. One end 15 of the diaphragm I lat In Fig. 1 the parts are exactly the same and operate in the same mannerexcept that the pump 19 is of the reciprocating t pe provided with the connecting rod 20. he end ofthe bar 9 engages a ball 21 on the end of the connecting rod 20. Obviously an orbital movement given to the end of the bar will give to the connecting rod 20 the necessary oscillating movement to actuate the pump.

What is claimed as new is 1. In a power transmitting joint for gas compressors, motor; a driving connection between the motor and the pump comprising a joint; a diaphragm sealing the joint; and a movable the combination of a pump; a l
